We are all, I am sure, aware of the objective and subjective reasons for division between Roman Catholic Church on one side and Eastern Orthodox Church on the other.
For nearly 1000 years learned and faithfull on both sides have said everything that had to be said regarding issues affecting the unity, as far as Theology and Ecclesial Politics are concerned, so there is no need to produce arguments for any position, because that will just produce more contra-arguments, and that will place my post in a situation of autodestruction.
The real question is NOT how much two sides are willing to compromise, but IS IT possible to compromise at all?
We are talking about dogmatic differences. I am, for one, sure that Roman Catholics are sure of their position and so are Orthodox of their. Please NOTE, so are Orthodox.
I will not go and try to explain, because, as I said before, we are all very aware of arguments and contra-arguments.
So what to do? In my honest oppinion, the re-unification is in Gods hands. Literally. That is to say, that as long as Rome goes one way and East goes the other there is NO ONE on this planet who can change the minds of our Clergy but God (To Him Glory now and ever and unto eternity).
This is not a bad news. Not at all. I am very happy to leave this problem to God (nothing new there).
May God, the Father of our Lord Jesus Christ and Holy Spirit (who proceeds from the Father eternally and from the Son in one time) help our Holy Church to overcome stupidity of time and make Lord's prayer regarding the unity of the Flock come to realization.
So, as to answer on the question in the title, yes, in time Unity will be reached, I am sure of this.
Orthodoxia i thanatos.
Our Most Blessed and Pure Theotokos and all the Saints pray to God for us, and firstly me, a sinner.
Holy God, Holy Mighty, Holy Immortal, have mercy on us.
....and in ONE, HOLY, CATHOLIC and APOSTOLIC CHURCH....
